Does anyone know if there is a difference in the way the Dell Receivers boot up and the way the rebadged sonic blue boot up? I ask because I have the following problem..

I was running dhcp from my linksys router and all my boxes were working fine - but I had no control over the IP addresses and it was a pain with tRio. So, I installed magik DHCP and disabled my linksys DHCP - now the rebadged sonic blues work and the dells don't. Is there some setting I have to set in Magik DHCP or something? Any help appreciated....
